Likewise for NetIdentical, but also if we plan to invoke during Resimulate too (even if non replicated, we use NetIdentical for comparisons. though this is probably a non practical use case).
enum { RequiresNetIdentical = (TNetSimCueTraits<TCue>::ReplicationTarget != ENetSimCueReplicationTarget::None) || (TNetSimCueTraits<TCue>::Resimulate) }
